8 Claims. 1

This invention relates to textile machinery and more especially to an apparatus for upset ting, breaking or crimping yarn which is to be subjected to sizing or dyeing, or bleaching operations after the yarn has been wound into tubular sion than the yarn wound about the medial portion of the package. It is evident that sizing solutions or dyes would more easily penetrate the yarns which are wound more loosely than the yarns which are wound tightly such as the yarn portions appearing at opposite ends of the packwould necessitate discarding the same.

It is, therefore, an object of this invention to provide apparatus for upsetting the opposite ends of cylindrically or conically-shaped packages of yarn so as to relieve the tension in the yarns yarns in each package uniformly throughout the package.

It is another object of this invention to provide vided for automatically discharging the crushed cone of yarn when the cup-shaped members are moved apart from each other and a new uncrushed cone of yarn is set between the cupshaped members.

It is another object of this invention to pro vide a machine for automatically upsetting, breaking or crimping opposite ends of packages to a position between bers and then moving the two cup-shaped meminvention having appear as the deered, retracted position;

Figure 5 is a vertical sectional along the line 55 of Figure 4;

Figure 6 is a vertical sectional view taken substantially along the line 63 in Figure 4, but

view taken bers M which support a top plate l5. paratus is supported on any suitable surface such as a floor I6.

Mounted on the plate 12 is a plurality of'bearing stands 20 on which a shaft 2| is rotatably mounted in bearing blocks '22 on the upper ends of the bearing stands 20. An electric motor 24 is also mounted on the table It, having a pulley 25 mounted on its motor shaft on which a belt 26 is mounted. This belt 26 is mounted on a pulley 21 which is a part of a reduction gear housing 28 which has a shaft 30 extending therefrom on which a plurality of pulleys 3| are mounted on which belts 32 are disposed and which belts are also mounted on pulleys 33 fixed on the shaft 2|. This shaft 2| has a pair of conveyor raising cams 35 secured thereon and also has a pair of cup operating cams 36 secured thereon, the table top I5 has a longitudinally extending slot 48 therein in which a reciprocating conveyor III is adapted to have movement. This reciprocating conveyor has pockets A, B and C therein formed from sheet metal or they could be cast and integral with the conveyor assembly. The pocket forming members are indicated by reference characters 44 for the end pocket members which are identical but opposite hand, and 45 for the intermediate pocket members which are identical. These pocket members Mi and 35 are secured to a base plate 46 which has an elongated bar l'I integral therewith. A pair of spaced angle bars 48 are secured to the lower surface of the table I5 and on each side of the slot 40 for guiding the bar 41. The bar "it has extending outwardly therefrom a bolt Eli which has a spacer 5| thereon and the outer end of this bolt 50 is slidably mounted in a slot 52 which is integral with a shaft and guide member 53.

This shaft and guide member 53 are mounted for sliding movement in brackets 54 and the lefthand end of this shaft 53 has a rectangular portion 56 which is adapted to have sliding movement in a guideway 51 which has integral therewith brackets 60 and BI which are suitably secured to the lower surface of table I5. Suitably secured to the lower surface of the table I5 is a pair of guideways 63 in which are mounted vertically sliding members 6 1 having a notch in their upper portion fitting the bottom and side of the bar 41 and these plate members 34 have vertical sliding movement in the guide members 63. The lower end of the members i l have a follower roller 66 mounted therein which is adapted to follow the respective conveyor raising cams 35. The vertically sliding members 64 are normally urged downwardly by tension springs I3 anchored in L-shaped brackets on the vertically sliding members 84 and to a suitable spring perch at the upper ends of frame members 'II.

The rectangular portion 56 of the shaft 53 has a pin 14 therein which extends into an elongated slot 15 in the upper end of a lever '53 which is pivoted at its lower end as at ll to a block I8 mounted on the lower platform It and this lever It has a cam follower roller 89 intermediate its ends which is adapted to follow the closed cam groove 8| in cam wheel 82 which is fixed on the shaft 2|. The conveyor mechanism is moved upwardly by the cams 35 and is moved longitudinally of the machine by the cam wheel 32 and the lever I6.

Mounted on top of the table I5 are opposed compressing devices and since the two structures are identical except opposite hand, like reference characters will apply. Each of these compressing devices comprises a pair of members 50 and SI secured to the table top having projecting ribs 92 on their proximate surfaces on which are adapted to slide a member 93 and the member 93 is confined in position by the strap members 34. Each of the members 93 has secured thereto by any suitable means, a cup holding member 95, each cup holding member 95 having a projection 96 which is suitably secured to the top inner end of the member 93.

This member 95 is penetrated by suitable bolts 9? which secure a resilient concave-convex cup member or die 98 to the member 95. Each of the members 93 has an elongated slot I00 therein loosely penetrated by a bolt IOI having a handle I32 fixed thereon and this bolt IIlI is threadably embedded in a rack I63 which meshes with a segmental gear I34 on the upper end of a lever W5 which is pivoted intermediate its ends as at I05 on a bracket I0'I secured to the lower surface of the table top I5. Each of these levers I05 have a follower roller I08 thereon adapted to follow the cup operating cam 36. The lower ends of these levers are hooked as at I I0 and each has a tension spring III secured thereto, the other ends of which are anchored to the bottom plate I2. From the position shown in Figure 6, the follower rollers I88 are on the low side of the cam and therefore the cups or dies 98 disposed fartherest apart, whereas in Figures 1 and 2 the cups 98 are fully moved towards each other to package crushing position.

Secured to the end of the apparatus is a bracket I It to which is secured a feeding chute I I4 comprising transverse channel members III; on each of which rests a pair of cut-away angle brackets or members I I! each of which has upright members H8 thereon. The lower ends of the angle members I II are slidably mounted in the channel members IIS and suitable means, such as bolts I20, penetrate the channel members H6 and the inturned portions of the angle members II'I for adjustably securing the brackets I I1 on each side to the channel members H6. The channel members IIB are secured to the brackets II3 by any suitable means such as bolts I23 and the bolts I20 are mounted in suitable slots I24 in the bottom wall of each channel member II6, whereby the angle brackets H1 and. associated parts can be moved apart or towards each other to adjust the width of the guideway according to the length of the tubes of yarn.

The upper ends of the members [I8 or brackets In each has secured thereto a bar I26. Bars I26 serve as guides for the upper portions of the packages of yarn. Suitably secured to the angle portion of angle brackets I H are elongated guide members or bars II8a and H822, each bar II8a forming a lower side guide and each bar II8b forming a bottom guide and, with bar members I26 as a top guide, a U-shaped delivery chute is formed upon which tubes of yarn or yarn packages may roll into the reciprocating conveyor M. Guide members I26, II8a and Heb are secured at their front ends to substantially angle shaped brackets I30 which have a horizontal grooved portion slidably mounted on a fixed rectangular elongated member I3I on the upper surface of the table top I5 and these brackets I30 have elongated slots I32 therein penetrated by bolts I33 embedded in the rectangular member I3I whereby the brackets I30 can be adjusted towards and away from each other along with the uprising brackets IIB.

An additional guideway is provided for conducting the tubes of yarn comprising L-shaped brackets I34 which likewise are inverted channel members slidably mounted on elongated rectangular members I35 fixed on the table top I5 and each having a slot I36 therein penetrated by bolt I31 by regulating the brackets I34 on one side apart from the brackets I34 on the other sideof the path of travel of the packages ofyarn. The brackets I34 have secured theretoguide bars I38 for guiding the yarn to the pressing cups 98.

After the packages of yarn have had their ends L-shaped brackets I49 having guide bars I4-I secured thereto and each bracket I40 having a slot I43 therein penetrated by a bolt I44 which is threadably mounted in an elongated rectangular guide member I65 mounted on the table top I5, the members I 40 being channel-shaped, as shown. A start and stop switch I58 is mounted in any suitable location on the machine and has a cable I5I leading from a suitable source of electrical energy, not shown, into the switch I50 and another cable I52, having wires I53 and I54, therein extends to the electric motor 24 to thereby furnish electrical energy to the electric motor 24.

M ethocl of operation It is to be observed that the package moving apparatus has an oscillatory and reciprocatory movement. In Figure 7, the package carrier or reciprocating carrier ll having the pockets A, B and C therein moves along the longitudinal slot 40 and in the position as shown in Figure 7 has reached the end of its stroke toward the feeding end of the apparatus and is now ready to advance the packages of yarn one step to place the package in pocket B in position to be operated upon by the upsetting cups 98. While the conveyor mechanism has moved on its way to the right in Figure 7, it will be observed that the cams 35 will be holding the conveyor in its uppermost position and immediately after the yarn package in cup B has been delivered to a point between the crimping c'ups 98, the cams 36 move to a position Where the high sides thereof Will move the crimping cups 98 toward each other to crimp that package of yarn under resilient pressure. At this position, the crimping cams 36 continue to move to where their low sides will be engaged by the rollers I68, thus allowing the springs III to move the crimping cups 93 away from each other as shown in Figures 6 and 8. Then the lowering cams 35 will be at a point Where the rollers 66 will be moved into engagement with the lowest surface of the earns 36 under tension of their springs it which will lower the conveyor mechanism 4! to where the pin 50 in Figure '7 will be resting in the lower end of slot 52 and will thus lower the members i t and 45 to where their topmost points will be below the surface of table I5 and then cam wheel 82 will start movement of the conveyor mechanism 4| back to the left in Figure 7 to the fully reversed position as shown in Figure 7 and then the raising cams 35 will start upward movement of the conveyor mechanism to cause it to return to the position shown in Figure 7 to automatically place packages of yarn which have rolled down the inclined guideway I I4 resting on bracket I I5 and the crushed package in pocket A will be moved outwardly into the discharge chute I39 having rails MI and the package in pocket B will be in a position to be crushed. This cycle of operation will continue as long as the machine is in operation.

In the drawings and specification there has been set forth a preferred embodiment of the invention and although specific terms are employed, they are used in a generic and descriptive sense only, and not for purposes of limitation,
